Nitrile-butadiene rubber (NBR) is a copolymer of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization.
It has excellent oil resistance, high wear resistance, good heat resistance and viscosity Relay is strong.
The disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance and slightly lower elasticity.
Nitrile rubber is mainly used in the manufacture of oil-resistant rubber products. There are five kinds of acrylonitrile content (%) in nitrile rubber,
such as 42-46, 36-41, 31-35, 25-30, 18-24. The higher the acrylonitrile content, the better the oil resistance, but the corresponding decrease in the cold resistance.
It can be used in air at 120℃ or in oil at 150℃ for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties.
It is widely used to make various oil-resistant rubber products, various oil-resistant gaskets, gaskets, casings, flexible packaging, soft rubber hoses,
printing and dyeing rubber rollers, cable rubber materials, etc. It has become indispensable in the automotive,
aviation, petroleum, photocopying and other industries elastic material
